I am working on updating an old website which uses font tags, to use CSS. The old HTML uses numeric font sizes (1-7) like this:
Some text
xx-small, x-small, small, medium, large, x-large, xx-large A set of absolute size keywords based on the user's default font size (which is medium). Similar to presentational HTML's through where the user's default font size is .
/* values */
font-size: xx-small
font-size: x-small /* */
font-size: small /* */
font-size: medium /* */
font-size: large /* */
font-size: x-large /* */
font-size: xx-large /* */
font-size: -webkit-xxx-large; /* */
